How to output 3 objects as 3 seperate nodes in a g3dj file
Figured it out!
I was exporting from blender to a wavefront obj file and then using fbx-conv to convert to a G3DJ one: this gave one node with 1 children with 3 parts.
Now when I export to an fbx file and convert to G3DJ using fbx-conv I get 3 nodes as required.
